PUMP-VALVE.

Specification of Letters Patent.

Patented Jan. 18, 1921.

Application filed November 14, 1919. Serial No. 338,028.

.l '0 all whom it may concern:

Be it known that 1, JAMES \V. SANDLIN, citizen of the United States, residin at Humble, in the county of Harris and tate of Texas, have invented certain new and useful Improvements in Pump-Valves, of which the following is a specification.

This invention relates to new and useful im 'irovements in a pump valve.

(hue ohiect of the invention is to provide a valve oi? the character described which is designed to be used in a pump, used in pumping wells, particularly ()ll wells, and which is so constructed that the wear on the valve and seat will the valve at all times to seat perfectly.

\Vith the above and other objects in view, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which. is given in this specification and illustrated in the accompanying drawings, wherein:

Figure 1, is a vertical sectional the valve,

Fig. 2, is a side view and,

Fig. 3, is a bottom end view.

Referring now more particularly to the drawings wherein like numerals of reference designate similar parts in each of the figures, the numeral 1, refers to the working barrel, whose upper end carries the valve seat 2, having the central fluid passageway This seat is retained in position by means of the valve cage 4, which is threaded on to barrel, and which clamps said seat in osition. The lower end of the pump rod not shown) is view of be uniform, thus causingv attached to the cage 4, and through this rod, said working barrel is reciprocated up and down. VVit-hin the cage at, there is a ball valve 5, which controls the passageway 3, and this valve has the depending stem 6, extending down through the fluid passageway 1:5, and the lower end of this stem is flattened and slotted formin fins 7, 7, which are oppositely beveled. is the fluid passes under pressure through the barrel 1, it operates against the oppositely beveled fins 7 to rotate the same, thus rotating the valve 5, slowly and causing it to wear uniformly and to thus at all times seat perfectly and prevent leakage through the valve.

What I claim is:

1. In a pump, a working barrel, a valve seat having a fluid passageway, a valve controlling said passageway, a stem fixed to the valve and extending down through said passageway, whose lower end is flattened and formed into the oppositely beveled fins and a cage iuclosing the valve.

2. In. a pump, a valve seat having a fluid passageway therethrougha ball valve controlling said passageway, a cage inclosing the valve and two oppositely beveled fins depending from the valve, and actuated by the fluid passing through the pump to rotate the valve.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES W. SANDLIN.
